It is an object of my invention to pro vide a. creel especially ,adapted for high-speed unwindi'ng. (for .example at speedsof 400 or `500 feet per minute or` higher) wherein the strands which maybe especially iine yarn, run freely through the .creel under no substantial frictional drag other than is caused by unwinding from their supplymasses, and wherein themany strands when stopped. may automatically be .clamped adjacent tother respective supply masse`s,thus to be held against entanglement. As is well known, the operator ofa creelmust often reach in among the strands to thread up the creel or `repair a strand. after breakage 4or exhaustion; .the creel of the presentinve'ntifon. is capable of securely holding all of the' many.v strands ofthe creel to prevent. any such slackness as would cause the strands to become `-tangled when accidentally'.

brushed. or touched by the operator.

Myinventionralso aims to provide` in its preierrede form, automatic clamping means adapted so to operate asto avoid tensioning actiombut on `the contrary to clamp the strands of the creel only when` they ,have ceased to run therefrom. This prevents the accumulation. of twist in the strands in rear-of their clamps, thus avoiding` one of. the causes of entanglement of strands in `a `creel. y

of. invention, and featuresL of eye- 19.

strand extending through the eye,.a light spring vertical angle irons lll connected yby .like long i` tudinal members, one of which is indicatedat 15 in Fig;` 4. These two sets of frame members are preferably tied together by transverse members such as indicated at`16. These transverse members 16 may conveniently extend across and similarly connect corresponding frame members at the opposite sidey of the creel,` leaving an inter` vening space or runway for the operator between the two halves or sides. Sincethe creelmay be symmetrical, only 'one oivthese is illustrated, Y

The inner vertical angle. irons l1li conveniently constitute supports for vertically spaced pins, pegs or spindlesvl adapted to'receive unwindtoV halves or sides ing supply strand packages or massesM. From C" each such mass the unwinding strand Y runsA to a porcelain eye 19 `extending through the' corresponding outer angle iron 11.` After "passing through this eye 19, the strand runs to the front end of. thevcreel, passing through a guide eye 20 in one or more outwardly projecting brackets` 21. Atthe front of the creel, all of the ends (ini cluding usually thoseY fromV both sides of the creel') are collected into a sheet or web S'by any suitable guiding means, such as apair of rolls" 23'; 24 and a suitable `reed 25; this sheet or web runs onto a winding beam or other. strandusing device which is not illustrated in Figspfl,

Means is provided Vfor' clamping each offthe manystrands i'nfthe creel at a point adjacent to its` supply mass.` Preferably such clamping means takes the vform of individual clampseach y'disposed-at thepoint at which the strand-just' leavingits supplymass joins the'group of strands L preferredA form of the invention, such'a clamp utilizes as a stationary or backing member `the above-described porcelain eye 19 (Fig. 3) through which the strand first passes.` A movable ymember adapted to clamp the strand against this eye lglpreferably consists of a circular `piece of metal leading vto thel frontend of the creel. In "the-yV `30 (Fig. 3) of about the same diameter asfthe To lforce theimember 30 againstthe by ineans of any suitable connection, .prefer-V1- ably a universal'tilting connection which insures that' the,v member' 30 will seat with certainty on the strand which extends through the eye '19".v As

illustrated, the member 30 is connected tor the spring 31 by a pin v'.54 `fastenedt'o the member mitthe strand to pass freely through the'V eye' without any clamping action.

The controlling mechanism for simultaneously operating the clamps includes vertically disposed rotatable rods 40, (Figs. 1 and 3) each having a pin 41 projecting therefrom in position to engage the inner surface of the spring 37, Vand Yso adapted to move the spring and member away from the eye 19. v.As shown in Figs. 1, Zand 3, each of therouter vertical angle irons 11 carries one of these rotatable rods, the rod. in each case resting on a suitable step or supporting bracket 42 which projects from the lower part of the angle iron, and being rotatably held in the corner of the two anges of the iron by suitable rvertically lspaced `clips 43. The numerous VVrotatable rods are preferably bent at their tops to form crank arms 45 which are engaged by reciprocating rods ,extending along the top of 'the creel. kThese rods, which may be suitably articulated if necessary, are connected by alink 51, arm 52 and shaft 53 toan arm 54, so that movement rof this arm 54 in one direction causes all of the rotatable rods 40 sif multaneously to remoVethecla-mping members 30gfrom Contact with the guide eyes 19, while movement of the arm 54 inthe opposite direction has the eiect of applying all of the clamps of the creel.

For automatically actuatingthe clamps in this manner, the, device preferably includes controlling meanswhich is responsive tothe movement of the strands from these unwinding supply masses.4 Such means, which is most conveniently in the form of a detector, preferably operates on Ythe sheet of yarn leading out from the frame of the creel at any distance therefrom.V While many Vforms `of mechanism competent to control the clamps in accordance With the movement. of the strands from theirV supply masses-may be employed, the preferred form utilized in the illustrated machine comprises a detector arranged to yrespond to the tension or slack in the sheet of i yarn." Assuming the sheet of yarn to be stopped, .the sheet will become less taut; the detector responds vtothis condition and causes vactuation to theresumed tautness ofthe sheet will cause the clamps to be removedl from the strands; thus the strands lin initially moving are not-pulled between the clamping surfaces.but run freely through their respective eyes 19.with no applied tension.

jAs illustrated, the detecting mechanism, utilized in conjunctionvvith the clamping means,

comprises a bar Yresting on'the sheet of yarn fand `*urged against the sheet byxany suitable means such as its own'weight, aided if desired by aweighttl.' The opposite ends of the rod 60 may beheld in arms 63 which are vfast on a suitably supported rotatableV shaft 64; and the ,weight 61 may be adjustably held on another `arm 66 alsoV fast to this shaft 64. The shaft 64 When the sheetof yarnL Vbegins again to move, the detector responding which extends between this crank 67 and crank 54.

The operation of the device will now be readily' apparent. When the sheet S stops, the slackness 0r absence of suicient tension therein will allowl 80 bar 60 to drop, thusactuating the abovedescribedconnections to` apply all of, the clamps of the creel. The rod 60 when itl rises in response to Athe tautness 'of the sheet which begins to move, Voperates the same connections to release all of creel with a warper which includes rolls', reeds 100 or the like for bringing the, many strands into a sheet at the Warper, the detecting mechanism may be mounted directly on the warper in posi-Y tionthere to act on the sheet.v For example, as

shown in Fig. 5 wherein a Warper '70 is provided 105 with guide rolls '71 and 72 and a reed 'Z3 Which acts to arrange vthe strandspina sheet directly at the warpenthe bar' 50 may be arranged .to act on the thus arranged sheet as it passes over the warperysothat the rolls A71 and ,'72, and reed 73 l10 need not be duplicated in the' creel. In this case, the shaft 64 which carries the bar 6 0 may advantageously be rotatablyumounted at the top of the warper on the'side nearest thel creel frame, 1

as shown. With this arrangement, the detecting mechanism need have no connection to thevstart'- ing, stopping, controlling ordriving mechanism of the warper, but operatesas described above in response to the condition of the sheetof yarn. :It should be understood that the present disll closure is for the purpose of illustration only and that this invention includes all modifica-l tions and equivalentswhich fall withinthe scope ofthe appended;claims.` p Iclaimz 1 o i,
